When he rose it was with the air of a man who had satisfied himself upon some important point. He then turned to Sir James.
"You might get those finger-prints," he said casually. "Get everyone together in the dining-room. See that no one leaves it for at least a quarter of an hour. Thompson will go with you."
"Then you think it was murder?" questioned Sir James.
"I would sooner say nothing just at the moment," was the reply.
Whilst Sir James Walton and Thompson were occupied with a room-full of domestics, talking in whispers as if in the presence of death, Malcolm Sage was engaged in a careful examination of the bottoms of all the doors in the house by means of a mirror placed upwards beneath each. He also removed the keys and gave a swift look at the wards of each.
He moved quickly; yet without haste, as if his brain had entire control of the situation.
One door in particular appeared to interest him, so much so that he entered the room and proceeded to examine it with great thoroughness, taking the utmost care to replace everything as he found it.
From the middle-drawer of the chest-of-drawers, he extracted from under a pile of clothes a thin steel object, some five or six inches in length, wound round with a fine, strong twine. This he slipped into his pocket and, going down into the hall, rang up the manager of the Lewes branch of the Southern Counties and Brown's Bank.
Passing into the library, he searched the drawers of the table at which Mr. Challoner had been found. In one of them he discovered the pass-book. Seating himself at the table, he proceeded to examine it carefully. Turning to the pockets at either end, where cancelled cheques are usually placed, he found both were empty.
When a few minutes later Sir James and Thompson entered with the finger-prints, Malcolm Sage was seated at the table smoking, his gaze concentrated upon the nail of the fourth finger of his right hand. With him a contemplation of his finger-nails in general indicated thoughtful attention; when, however, he raised the hand and began to subject some particular finger-nail to a thorough and elaborate examination, it generally meant the germination of some constructive thesis.
